Very solid first episode, left me wanting more without relying on a cliffhanger. The music, cinematography, and acting is all on-point. The feeling of being back and Westeros gave me chills, despite the distrust S8 of GoT left within me.
My only complaint is that the pacing made certain parts of the episode feel awkward until after they were explained, and that overall the story seems to be moving a bit too fast right off the bat - although that may end up being a good thing.
